If you're looking for the originals, you'll struggle, since as far as I know Class D are no longer trading. I'm guessing they have compression drivers in, rather than piezos. Piccies would help, as would any specs written on them. Do they screw in, or bolt on?



I think you'll be forced to get something that looks close, and hope.

i have tried a few places, they are compression drivers, and they are a 4 bolt, bolt on unit, most drivers are 3 bolt, hence the trouble getting replacements,
I guessed class-D had ceased trading as no reply to mails, but with their customer service in the past i was not expecting much of a reply

Take a picture of the driver and post it up. Someone will surely be able to point you in the right direction.

[wayne_uk]

i'll get one taken the weekend

Indeed they are. I myself have a project in progress which may use the same horn mountings. Oh look, 4 hole compression drivers, what a coincidence. (http://www.ebay.co.uk/itm/370895082642?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648)

There may easily be others, I don't know. I have these in mind for said project. I don't guarantee that they fit the mountting plate, but I'd suggest contacting the seller, and ask what the PCD ( Pitch Circle Diameter ) is. That's a circle which passes through the centre of all the mounting holes.

Keep us posted.

I seem to remember speakers identical to the class D ones were being sold under a different brand name, trouble is I can't remember what it was, does it ring any bells with you Peter?

Sort of. AC Euro had the same cabinets, but Eminence drivers. I once saw boxes and boxes of them in the warehouse. Latterly some cabs labelled " Konig" ( I think ) were being sold on the Class D website. I don't think these shared the same drivers, though I'm only guessing there.

Give Blue Aran a call as they produce their own drivers and supply a good range.
Andy is a great bloke and great company - Just had an HDA curry with him.

Mention Toby as he always moans at me that I don't buy anything ;)

I think i may have found the drivers, look the same, bolt holes are the right distance, throat may be close but not too bad, and the rating looks to be ok, the original does not have any details or specs on it just an 8ohm sticker.
but you get the idea what i require

Hmmmm. did you check the location? It's across the pond.
Why not have a word with Thompsons, who are in this country, supply Pyle drivers, were sugested by someone, Oh look, 4 hole compression drivers, what a coincidence. (http://www.ebay.co.uk/itm/370895082642?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648)
and although dearer, are higher rated, and a lot louder. Now whether you will need extra loudness in this area, I don't know. I do know know that I bought some very cheap ones for a project, which work superbly, but just aren't loud enough. We're in " suck it and see " territory here, sadly.

[wayne_uk]

all of theirs are m6 bolts with a 90mm hole centres
mine are m5 with a 75mm hole centres, i can drill out the mounting bracket to accomodate m6 bolts but reall dont want to re-drill the bracket for 90mm hole centres, i will still keep looking for a uk company to supply me, someone somewhere will do them i'm sure

Ah. Fair enough then. :o:D:D

Here's an option then, as Toby suggested from Blue Aran. bolt to screw adaptor (http://www.bluearan.co.uk/index.php?id=PAUPC35)
Screw on drivers are a doddle to find.

will fit an AC Euro ACP115T (as referred to earlier by Excalibur). M5 holes that correspond exactly to the mounting bracket. I know this as I fitted one as an emergency measure to one of mine and worked fine.
May still have a pair of them in the garage for postage only ?, if I can find them ;)

Funnily enough, those are on my ebay watch list. Nice enough price. All I'll say is that while they will undoubtedly fit the mountings and make a noise, they may not make enough noise. I bought some screw in ones with similar specs, cos they were cheap. Very cheap. They sound really lovely, and smooth, but they're just too quiet. As Kernow says though, cheap enough to fit as a stopgap while you source a better solution. Good luck, keep us posted as to what you get, and how you get on.

They're rated at 150W/94db, and although I know you can't hear watts :doh:, the HF amp on an SRM450 v2 only kicks out 100W. Should be more than adequate HF for a 15" Full range cab ?

As are mine, it transpires. Thanks for the heads up, could have saved me from making a pig's ear of the whole job.

Indeed. But the whole of those 100 watts find their way to the HF unit in the Mackie. In a passive cab like the Class D, many of them are soaked up by the crossover. Coupled with an inefficient driver, this drops the HF output quite a bit.

I fitted some equivalent units in my Class D cabs, and they just can't keep up with the equally inefficient 15" drivers. Next time, the ones I use will be louder.

[Excalibur]

Here we go. A possible solution. (http://www.bluearan.co.uk/index.php?id=PAUPC25) Fiver plus carriage, then you can use any of the screw in drivers readily available.

[wayne_uk]

I did see them, lol
the page is in my favourites menue, i have a number of routes to look at, i'm surprised that not a lot of uk companies do the pyle unit that i posted.
had a good search around tinternet and most are from the usa

[Excalibur]

Since I wanted a pair myself, I contacted Thompsons ( Who I have found good to deal with. They're based in Macclesfield, but hey, nobody's perfect. :D )
The latest reply was :

Hey there,

Okay then you want a pair of these PDB552 Pyle. They are great quality build and high power... But cost peanuts.

Thanks.

Jed

I haven't had an exact definition of " Peanuts ", but sounds promising. I'll keep you posted.

STOP PRESS:

Blimey, peanuts aren't cheap this time of year. Thirty quid each delivered. Jesting aside, that's not a daft price, in my opoinion.

[wayne_uk]

Update, i bought the pyle units, the bolts supplied were a little long but i had some shorter ones i could use.
fitted the units, they have a solid feel to them and were heavier than the ones i originally had fitted, fired up the system and
had a listen, i was impressed with the sound, mids were clear and the tops were not too harsh.
so i now have my speakers back, thanks to all that replied it worked out well in the end.
